Application filed December 26, 192s. seria1no.e2s,4e7. i

This invention relates to show cases generally, and is particularlydesigned for use in show cases of the display refrigerator type.

As is well known in the "art, these refrigerator display cases usuallyhave the rear walls provided with heavy insulated doors pivotednearthebase of the display case to swing about horizontal pivot axes.

The main object of the present invention 7 is to provide these doorswith means to prevent their free edges from swinging into contact withthe floor or platform on which the display cases may be located.

Another object of the invention is to provide the closing ends oflsuchdoors with sup- 'ports'adjustable to support such ends, when the doorsare opened, substantially parallel with the bottom of the display case.y

A further object of the invention lies in the design of these show casesto cause the innerface of each door to occupy: such position when fullyopened as to serve forslidably supporting a sliding trayadapted to heslid into and out of the show case for the purpose of receiving goodstobedisplayedtherein.

Other objects of the invention will become apparent as the detaileddescription thereof proceeds.

As shown in Figurev 1, the display case is provided at its rear side 2with doors 3,

which gives access to the interior of the show case. Each door is of theheavy into sulated type peculiar to display cases of this nature; and,asshown, are hinged to the rear Figure 1 is a perspective view of a showporting position.

While the slotted rods 7 and 8 are sufiicient to hold the doorshorizontal when; opened it is also desirable to PIOVldBthBSB doors withadditional supports connectedto theirfree ends and adapted to beadjusted into contact with the floor or platform supporting the showcase, so that the doors when in open position may servew'to support thesliding trayswhich move into and out of the show case..Additionallsupports of the type referre'dltoare shown in Figures '1 and2 as :beingl adjusted into, contact with the floor to support the door 3in horizontal-tray sup,

The tray 16 is provided with cross rails 18 and 19 suitably connected tothe side rails 17 and the slats 18 extend between the rails 18 and 19.The front rail 19 is provided with handles 20 adapted for use in movingthe tray 16 into and out of the display case. The outer ends of the siderail 17 are provided with castors 21 adapted to slide on wear plates 22secured to the inner face of each door 3. 1 f

The guideways 15, the sliding tray 16, and the doors 3 are soconstructed and arranged that when the door is open and properlysupported on the supports 10, the tray may be drawn out on the doorfully supported by the castors 21 and without binding in the channels ofthe guideways 15.

In order to prevent the tray 16 from being drawn out beyond the limit ofthe door 3, the guideways 15 and tray 16 are provided with stopmechanism shown fully in Figures 3 and 4. Each guideway 15 has a screwthreaded bolt 28 threaded thereinto with its end closely adjacent to theinner face of a rail 17 and the rail 17 near its inner end has fixedthereto a cam-slot member 24 adapted to contact, when the tray 16 isdrawn out on the door 3, with the bolt 23 to limit the outer movement ofthe tray.

I claim:

1. A casing having an opening in a side thereof, channel guidewayshorizontally supported parallel to each other in said casing, a trayslidable in the channels of said channel guideways through said opening,a door for said opening hinged to said casing to swing about ahorizontal axis, means for supporting said door, when opened, parallelto said guideways, and means for slidably supporting the outer end onlyof said tray on the inner face of said door when in open position.

2. A casing having an opening in a side thereof, channel guidewayshorizontally supported parallel to each other in said casing, a trayslidable in the channels of said channel guideways through said opening,a door for said opening hinged to said casing to swing about ahorizontal axis, means for supporting said door, when opened, parallelto said guideways, means for slidably connecting the outer end of saidtray to the inner face of said door, and cooperative means on said trayand guideways for limiting the outward movement of said tray relative tosaid door.

In testimony whereof I affix my signature.
